%X Slotted tube cavity has been used in rubidium atomic frequency standards, but the microwave field distribution inside the cavity is unknown. Recently we calculated the microwave field distribution inside the cavity using high frequency structure simulation software (HFSS), and measured the field distribution experimentally with the optical-microwave double resonance method. The theoretical and experimental results were found consistent with each other. The results showed that magnetic lines of the microwave field lay along the cavity axis, impling that the cavity is suitable for applications in atomic frequency standards. The results also showed that the field distribution is spatially inhomogeneous, suggesting that the cavity needs to be improved further, since field inhomogeneity could affect the signal intensity of atomic clock transition.
